lightbox image in article

Hi,

How to insert images with lightbox effect? I think, that is some css class. I mean images next to main image - images per ex. in the middle and the end of article.

I mean also (if is important) both k2 and joomla aricles.

thank you

The easiest way is to use some 3rd party extension or in this case if this should work in both K2 and Joomla articles. Template by default don't provide this kind of functionality.
